204 ALBARDIA FURCATA. 



Probably the lost Byas microcerus Ramb. from the Antilles 

 ought to be placed also in the neighbourhood of Alhardia. 

 Me. Lachlan since long possesses a couple of Albardia from 

 the same locality. 



Ascalaphus immaculatus, Olivier.

p. 238, n. 13, note. 



In the collection of the Leyden Museum I found an 

 Ascalaphus with the name imrnaculatus Oliv. in the hand- 

 vsrriting of the late Mr. Snellen van VoUenhoven. As Mc. 

 Lachlan mentions in his » Attempt towards a systematic 

 classification of the family Ascalaphidae", in the genus 

 Haploglenius an undeterminable Ascalaphus imrnaculatus 

 Oliv., I could not doubt that this was Olivier's type. It 

 bears on the label of origin »Raye, Amer. raer." Also 

 from the same collection »Raye" from which we possess other 

 types of Olivier of Neuropterous insects. The locality »Amer. 

 mer." is the same as Olivier mentions and his description 

 being insufficient it is impossible that Mr. Snellen v. Vol- 

 lenhoven, who never occupied himself with Neuroptera, could 

 make this determination. 



The specimen is in tolerably good condition. But one of 

 the antennae is wanting and the villosity is so dirty that 

 it is impossible to distinguish the colours of it. It is a Haplo- 

 glenius which has much relation to Episperches and the 

 length of the wings, as well as the colour of the pterostigma, 

 agree very well with Walker's clarnnosus. The specimen 

 is probably a male, the length of the abdomen being larger 

 than in Walker's clarnnosus which is a female, but I 

 cannot find anything of the prothoracical valve. Not having 

 damnosus Wlk. at my disposal, I cannot surely explain 

 this question.
